Coding OCR with machine learning from scratch in Python — no libraries or imports! (From Scratch #2)

Показать описание

Our program uses the k-nearest neighbors algorithm to classify images from the mnist and fashion-mnist datasets, meaning it takes digits (1, 2, 3, …) and garments (shoe, t-shirt, …) and guesses what they are (classifies them). It can get up to 93% accuracy on mnist. I wanted this to be a simple introduction to machine learning for those not very familiar with it.

Because this is a recording of a live stream, you'll hear me sometimes talking to the chat.

What would you like to see me code from scratch next? Let me know in the comments! :)

Wishing you a swell day,
Vlad

I've just started learning machine learning and I really like this video - you explain everything very clearly. It's nice to see how to do this from scratch instead of using some huge libraries.

Brilliant tutorial, everything is so clearly explained, and it actually is from scratch.

This was so refreshing, you made it way better than some full-of-pride professors at some universities. Thanks so much mate. Could you do at some point the most basic “non-lazy-training” algorithm from scratch? Whichever you deem is fine

Thanks for sharing, PaddleOCR seems friendly for training the OCR models. Could you please shoot a video about how to use PaddleOCR?

Hey, the website you've got those files from now requires a password and username to get in. Is there another place we can get the files from?

Instructional video about machine learning, it would be good if you could make a video on how to configure vi with python with the basic instructions. Best regards.

Good video but christ, presentation wise and viewer experience, an absolute car crash!! Max res 720P, you should have zoomed a bit more!!! That background chance from black to white just fucked my eyes up at 14:25
